The truth about nutrition is always in flux. One day coffee is a carcinogen, the next it’s a potent antioxidant. Carbs used to be the devil, now (the right kinds) are the staple of a well-balanced diet.

What’s healthy seems to change regularly, and 2016 was no exception, which is why we’re looking back at the biggest nutrition discoveries of the year.

To recap: Remember how we all suffered from serious false hope when butter was said to be healthy? (That is, until another study quickly squashed that dream and confirmed that saturated fats have been and always will be bad for us…sigh). Or that time we gasped when we learned that in addition to being ineffective, dietary supplements may be flat-out fatal? How about the happy dance we did when our nut butter obsession was deemed a-ok?
